# Makefile de GRISLI avec gfortran


# FT options de compilation
# LK options de link

# Rappel de quelques options interessantes 
#-------------------------------------------
# faire imperativement attention a l'arithmetique

# -fbacktrace 
#   Specify that, when a runtime error is encountered or a deadly
#   signal is emitted (segmentation fault, illegal instruction, bus
#   error or floating-point exception), the Fortran runtime library
#   should output a backtrace of the error. This option only has
#   influence for compilation of the Fortran main program.


# -fbounds-check  
#  Enable generation of run-time checks for array subscripts and
#  against the declared minimum and maximum values. It also checks
#  array indices for assumed and deferred shape arrays against the
#  actual allocated bounds and ensures that all string lengths are
#  equal for character array constructors without an explicit typespec.
# 
#   -fcheck=bounds idem mais plus de possibilites dans le check


#   Some checks require that -fbounds-check is set for the compilation
#   of the main program.

# -ffree-line-length-n
#   Set column after which characters are ignored in typical free-form
#   lines in the source file. The default value is 132. n may be none,
#   meaning that the entire line is meaningful. -ffree-line-length-0
#   means the same thing as -ffree-line-length-none.

# -ffpe-trap=zero,overflow,underflow 
#  tells Fortran to trap the listed floating point errors (fpe). Having
#  zero on the list means that if you divide by zero the code will die
#  rather than setting the result to +INFINITY and
#  continuing. Similarly, if overflow is on the list it will halt if
#  you try to store a number larger than can be stored for the type of
#  real number you are using because the exponent is too large.

# -lsz pourrait etre (szlib) un outil de compression hdf5 mais n'est pas installe (non libre)
